Bambu Lab H2S
About the Bambu Lab H2S
The Bambu Lab H2S is a large, fully enclosed, high speed CoreXY 3D printer that can also be configured as a laser engraver and cutter, a cutting plotter or a pen plotter. The print volume is 340 X 320 X 340mm. The maximum peak speed is 1,000mm/s, driven at an acceleration of 20,000mm/s². The high-flow nozzle (40mm³/s standard, 65mm³/s optional) can be heated up to 350°C and it prints onto a dual-sided removable magnetic flexible steel PEI-coated plate that can be heated up to 120°C. The enclosure is actively heated up to 65°C and vented through an activated carbon HEPA filter so that temperature sensitive filaments and materials that generate hazardous fumes like ABS and ASA can be safely printed. The printer automatically opens a top vent, admitting cool air for printing low temperature filaments like PLA, or closes all vents and exhausts, recirculating heated air for high temperature filaments like ABS. The printer uses nozzle strain-based automatic leveling and automatically sets Z offset. An optional "vision encoder plate" and vision encoder sensor increase XY motion accuracy to 50µm. There's a 1920 X 1080 live view camera and a 1600 X 1200 toolhead camera. AI examines the nozzle camera images, looking for nozzle clumping, air printing (extrusion failure), and spaghetti (unadhered filament). It examines the chamber live view images before a print, double-checking the installed build plate type and nozzle type. It also looks for objects inadvertently left on the print bed. The custom extruder motor uses positional feedback to accurately control extrusion and detect filament grinding and clogging. The tooless quick swap nozzle assembly is retained by a magnet and locked in with a clip like the nozzle in the Bambu Lab A1 series. The printer connects to the network by dual-band Wi-Fi and can be controlled by Bambu Studio slicing software, the Bambu Handy app on a phone or tablet, or the 5" full color touchscreen on the printer. The H2S uses the AMS 2 Pro for multifilament printing, included with the H2S AMS Combo. The AMS 2 Pro is a four filament feeder, sealed and heated up to 65°C to act as a filament dryer. An electromagnetically-controlled vent releases moisture and the filament spool is slowly rotated to evenly heat the filament. Filament drying parameters are automatically set by RFID readers reading the RFID tag on each Bambu Lab spool. These readers also send filament data to the printer. The filament feeds through wear-resistant ceramic ports to an easily-accessible four tube pathway and filament is fed at high speed using brushless servo motors, saving time during filament changes. The AMS HT can also be used with the H2S. It's a single filament feeder and dryer that functions like the AMS 2 Pro but is capable of heating up to 85°C. It also has a temperature, humidity and drying time display and is equipped with a bypass outlet for soft or brittle filaments that can't be pushed up the tube. Up to four AMS 2 Pro units and eight AMS HT units can be connected to the H2S for up to 24 filaments. You can also use older AMS units, but these don't have filament drying capabilities.
Benefits of the Bambu Lab H2S
Modern mainboard features - Many 3D printer features relate to the version of the mainboard and firmware, including features like resuming prints after a power failure and support for silent stepper motor drivers for quieter printing. Newer boards also include safety features like thermal runaway protection which shuts the printer down if it detects issues with overheating.
Auto bed leveling - auto bed leveling will ensure your prints have perfect first layers every time and greatly reduce issues with bed adhesion. When using an auto-leveling system, the probe allows better tolerances for slightly warped print beds by measuring and compensating for any inconsistencies. Without this feature, you'll need to adjust the bed level manually using nuts on each corner of the print bed.
Has touch screen - having a touch screen isn't a deal-maker or breaker, but it is a convenient feature that makes it easier to navigate the interface when you are printing files and configuring 3D printing settings.
Fully assembled - This 3D printer is shipped completely assembled, and is ready to plug in and start using as soon as you unbox it. You will still need to follow the included calibration procedures, but this will not take a significant amount of time.
Direct drive extruder - Direct drive extruders are mounted right above the hot end, and push the filament directly into it, as opposed to a side mounted bowden extruder setup. We prefer direct drive extruders to bowden since they are less prone to jamming and typically require less maintenance. they also are much easier to use with flexible materials
PEI build surface has good balance of adhesion and part removal - PEI beds are one of the more premium build surface options, and for good reason. They offer great first layer adhesion with no spraysor other treatments, and can be flexed to quickly remove parts. You'll need to clean the bed with a solvent like acetone or IPA every so often to maintain the bed's adhesion.
Generous Build volume - A larger than average build volume means that you will be able to print larger parts without the need to split them into pieces and attach them together, which is especially useful with functional parts. If you have the room for the larger footprint, we definitely recommend going with a larger 3D printer, since you can always print small parts on a larger printer.
Wireless printing - In addition to the standard USB and SD card connections, you can connect wirelessly to this printer to print from your computer or mobile device.
Linear rail motion system - Linear rails provide added stability to the moving parts of the printer, allowing higher printing speeds without sacrificing quality. Keep in mind that the most important factor to consider when optimizing for print speed is the flow rate of filament, which depends on the hot end and nozzle size moreso than the motion system.
All-metal hot end - An all-metal hot end allows for printing at high temperatures up to 300C, while standard hot ends are capped at 260C before the PTFE material begins to degrade. All-metal hot ends are also less susceptible to jamming, and do not degrade as fast.
CoreXY Kinematic System - A CoreXY 3D printer kinematic system uses two stationary motors to move the print head in the X and Y directions, resulting in faster and more precise movements compared to traditional printers. By separating the movement of the print head from the movement of the build plate, the CoreXY system is able to avoid the added weight and momentum of a moving build plate. This results in less vibration and better control of the print head, allowing for faster and more precise movements. Additionally, the CoreXY system can print at higher speeds compared to H-bot systems because it only needs to move one motor for each axis of movement, reducing the overall weight and inertia of the system.
Enclosure - An enclosure seals air around the print area. This holds warm, still air around the print area and is essential for printing temperature-sensitive materials like ABS. Enclosures also prevent particulates and gasses from being emitted into the surrounding area, increasing safety. They also greatly reduce printer noise.
Dual gear extruder - A dual gear extruder grips filament from both sides and can exert much more force on the filament before slipping. It helps with all filaments but especially with flexible, slippery TPU.
Where to buy the Bambu Lab H2S
Brand Summary: Bambu Lab
Bambu Lab, founded by ex-DJI engineers in Shenzhen, has made waves in the 3D printing industry with its focus on speed, innovation, and user-friendliness. While it began its journey through a successful Kickstarter campaign, raising $7 million in a month, the brand has since had its share of growing pains, including shipping issues and firmware bugs. The company's commitment to creating intuitive, precalibrated 3D printers like the X1-Carbon and P1P is commendable, but some users have found limitations with the proprietary components and software. Despite these challenges, Bambu Lab boasts a large community of dedicated users across various platforms and continues to evolve in its offerings and customer service.
